IMPROVEMENT lN LARD-PRESSES.

Specification forming part of Letters Patent No. 152,014, dated June 16,1874; application filed January 14, 1874.

To all whom it may concern:

Be it known that I, RADIUND SEEBURGER, of Des Moines, in the county ofPolk and State of Iowa, have invented a Sectional Lard- Press Cylinder,of which the following is a specification The object of my invention isto provide a means for readily removing the pressed cake of meat-scrapsfrom which the oil or lard has been extracted while in a cylinder andunder screw pressure. It consists in a double cylinder formed in halvesor sections, and hinged together in such a manner that ,it can bereadily closed to receive and retain oily and juicy substances to besubjected to pressure, and then easily opened and expanded to allow thecompressed solid matter to drop out.

My drawing is a perspective view, illustrat ing the construction andoperation of my invention.

A A is the inside cylinder, made of sheet metal and banded withstrap-iron. The two sections are hinged together in any suitable manneron one side, and provided with loops or eyes a a on the opposite side,through which a rod, b, is passed, when the cylinder is closed, to lockand hold the sections rigidly together. This inside cylinder isperforated, to allow the oil or liquid to strain through. It may vary indimensions, and may be cast metal, or made of any suitable sheet metal.Handles may be attached, for the purpose of lifting it about. Nos. 1, 2,3 representa series of bent stay-rods or bars, that are riveted orotherwise secured at the top and bottom of the inside cylinder A, forthe purpose of connecting the larger outside cylinder, and to form anannular chamber between the two cylinders. B B is the outside cylinder,also formed in two vertical sections. It is riveted or otherwise rigidlyattached to all of the stays excepting No. l, to which the sections aresecured in such a manner as to produce a flexible joint that will expandand contract and accommodate itself to the movements of the hingedinside cylinder. 0 0 represent screwbolts or set-screws passed throughhorizontal slots in the left section where it overlaps the rightsection, and then through holes in the right section, to enter femalescrews cut into or attached to the No. l stay-rod. By this means theedges of the outside cylinder are allowed to lap and retain the liquidwithout interfering with the working of the hinge-joint of the insidecylinder. The edges on the opposite side of the outside cylinder projectand lap, and are retained in place, when the double cylinder is closed,by means of the eyes a and rod 1), or their equivalents. d (1 representelastic washers or springs, that are retained on the screws 0 by theheads of the screws, in such a manner that they will constantly pressthe sliding lap-joint ot' the outside cylinder to keep it from gaping.Both ends of both cylinders are open. When the complete double cylinderis closed and placed in a press, its bottom will rest in a pan or on atlat base, which will close the bo toin,'excepting the month or openingthat is required to allow the liquid to escape into a suitablereceptacle. \Vhen the liquid has been pressed out, the solid substanceremaining can be carried in the cylinder, to be emptied whereverdesired.

By withdrawing the rod 1) from the loops or eyes a, the closed cylinderwill be unlocked, and easily opened and spread, to allow the compressedsolid cake to drop out.

My invention is specially designed for a lard-press, but can bezulvantageously used for pressing fruits and other substances from whichliquids are to be extracted by pressing and straining.

I claim as my invention The combination of the sectional cylinders A andB by means of the series of stays Nos. 1, 2, 3, the eyes a and rod 1),and the setscrews c and springs d, substantially as described, and forthe purposes specified.
